    • Busbar current transducer with suppression of external fields and gradients 

      Author: Ripka, Pavel; Chirtsov, Andrey
      (IEEE, 2018)
    • Current Sensor in PCB Technology 

      Author: Ripka, Pavel; Kubík, Jan; Duffy, Maeve; Hurley, William Gerard; O’Reilly, Stephen
      (IEEE, 2005-06)
      A novel DC/AC current sensor works on the fluxgate principle. The core in the form of a 7/10-mm ring made of electrodeposited permalloy is sandwiched in the middle of a printed circuit board (PCB), whereas the sensor ...
    • Double Coil-Less Fluxgate in Bridge Configuration 

      Author: Butta, M.; Ripka, P.; Navarrete, Joaquín Pérez; Vázquez, M.
      (IEEE, 2010-02)
      In this paper, a new method for excitation of coil-less fluxgate is presented. The purpose of this method is to reduce the spurious component of the output voltage, allowing us to increase the amplification. The method is ...
    • Linearity of Pulse Excited Coil-Less Fluxgate 

      Author: Butta, Mattia; Ripka, Pavel
      (IEEE, 2009-10)
      In this paper, we study the open-loop linearity of pulse excited coil-less fluxgate. Narrow current pulses can be used instead of classical sinewave for the excitation of the coil-less fluxgate. This method has shown several ...
    • Magnetic Microwires With Field-Induced Helical Anisotropy for Coil-Less Fluxgate 

      Author: Butta, M.; Ripka, P.; Infante, G.; Badini-Confalonieri, G. A.; Vázquez, M.
      (IEEE, 2010-07)
      We present a new method for production of magnetic microwire with helical anisotropy. Coil-less fluxgate sensors are generally composed of a bimetallic wire excited by an alternating current; in order for the wire to work ...
    • Pulse Excitation of Micro-Fluxgate Sensors 

      Author: Ripka, Pavel; Choi, San On; Tipek, Alois; Kawahito, Shoji; Ishida, Makoto
      (IEEE, 2001-07)
      Miniature fluxgate sensors with symmetrical closed core elements on both sides of the planar coils were manufactured using standard microtechnology. The new sensors have shown substantial improvement over the standard ...
